Regarding the TCAS thing - in UK airspace you are specifically required NOT to announce that you have an aircraft on TCAS. Its a waste of time and adds nothing. Not only that I am extremely wary of saying anything that might indicate that I have any responsibility for separation.
The whole thing about reconfiguring bleeds after takeoff is quite surprising. I know exactly how the aircon and press system works, but this is so critical to safe flight that making sure you have done it correctly is crucial. Enough people have screwed this up to make the bleed reconfig checklist an essentially mandatory step in my opinion. I think sometimes we have to remember that proving that we are ace pilots is not often compatible with passenger transport operations. Bleeds off takeoffs are just not common enough on modern types to be a safely executed memory procedure.
